在 Linux 上安裝 APC UPS 管理工具

在 Linux 設定監控一台不斷電設備 APC

APC 官網並不提供 Linux 的軟體，所以找了一個 ↓↓

apcupsd http://www.apcupsd.org/
A daemon for controlling APC UPSes

下載它然後安裝

tar zxvf apcupsd-3.14.14.tar.gz
cd apcupsd-3.14.14
make clean
./configure --enable-usb
make
make install

接著，先確認 USB 資訊有抓到 APC 設備

cat /proc/bus/usb/devices

T: Bus=02 Lev=02 Prnt=02 Port=03 Cnt=01 Dev#= 4 Spd=12 MxCh= 0

E: Ad=81(I) Atr=03(Int.) MxPS= 8 Ivl=100ms

安裝完 apcupsd 後，它的設定檔，官網有提到的基本的設定 (照預設即可，我這邊是用 USB 連接)

more /etc/apcupsd/apcupsd.conf

# Simple USB Configuration
# If you have a USB UPS, the essential elements of your apcupsd.conf file should look like the following:
## apcupsd.conf v1.1 ##
UPSCABLE usb
UPSTYPE usb
DEVICE
LOCKFILE /var/lock
UPSCLASS standalone
UPSMODE disable
EVENTSFILE /var/log/apcupsd.events # 事件記錄

啟動 apcupsd

service apcupsd start

驗證 apcupsd

執行

apcaccess

就可以看到現在 APC 的資訊

apcupsd 有提供 apctest 指令，可作一些系統測試，但前提要先停掉 apcuspd

apcupsd 也有 web CGI 可用 ↓↓

http://ssorc.tw/apcupsd/multimon.cgi
http://ssorc.tw/apcupsd/upsfstats.cgi
http://ssorc.tw/apcupsd/upsimage.cgi

設定一下 apache config

more /etc/httpd/conf.d/apcupsd.conf

ScriptAlias /apcupsd/ /var/www/apcupsd/
<Directory /var/www/apcupsd/>
    DirectoryIndex upsstats.cgi
    Options ExecCGI
    order deny,allow
    deny from all
    allow from 127.0.0.1
    allow from all
</Directory>

其它

System Shutdown Test
This is an intermediate test that you can do, for all UPS models before doing the Full Power Down Test. First modify the /etc/apcupsd/apccontrol file so that in the killpower case, the line that re-executes apcupsd with the –killpower option is commented out. The original line probably looks something like:

${APCUPSD} –killpower
